7 This invention relates to water coolers in general-,fand particularlyto-that type of coolers in which the cooling medium of ,themechanical orcirculating type. y The object of the invention is toprovide a watercooler iwhichis exceedingly efficient operation, which is small andcompact in ,construction, and which canbe quickly and 1 5 economicallymanufactured and assembled. Another object is to provide a water coolerwhich has a cooling tank of relatively large K 7 areal-sothatthefiuidtherein may-be quick- I lycooled and maintained at a normallyeventemperature.

i, 15 Another, objectis to provide a w-ater cooler whichis provided withaplurality of addi- I itional cooling compartments or chambers whichareaccessible from the outside of the ,vcooler.

v, cooler-which hasarelativelylarge water storage tank which cooled bymeans of a mechanical or circulating refrigerating system whereby'spac'emay be preserved or provided within; the refrigerating chamber a for thereception of, ice

pmanufacturing ice cubes.

g A still further object is to provide new and novel Valve, means forestablishing communication between tliestorage tank and the main.fluidorwater supply. V a

. Other ob'ects and advantages will hereintrays or pans for a afterappear.

The invention comprises in generala cas- 'ing' in whicharefrigeratingchamber is arranged for cooling the water storage tank. I Amain watersupply or bottle is arranged a I 1 aboveth casingandhas communicationwith thest'or'age tankwhereby a relatively large quantity of water ismaintained in cont-act a with the cooling medium sothatduring eras "naryuse, the water in the tank will be kept.

I at a substantially even temperature. A cool- Ling? medium, whichinthis instance is shown zasflbeing a brinejcirculating' system, isarrangedpartially jabo'utthe water storage tank; anda-plurality ofcompartments is arf rangedadjacent the cooling medium :for the receptionof bottles or other articles. which A further vobj 'ect is yto provide awater" usual and conventional manner. .is connected to the upper part ofthe tank COOLER V 1 929. i Serial No. 355,255;

are cooled byfthe cooling medium and which are independent of the waterstorage tank. plurality of smaller compartments is preferably arrangedbelow the bottle compartments, and these latter compartments containdrawers or trays for making ice cubes, if desired. f

v, Thei accompanying drawings illustrate a selected embodiment of theinvention and the views therein are as follows:

Fig.1 is a detail vertical sectional view through the water cooler;

Fig. 2 is a similar view taken at right angles to Fig.1; 7 i

Fig. 3 is a sectional plan view, and Fig; 4 is a detail sectional viewshowing the valve mechanism which connects v the water supply with thewater storage tank. Referring to the drawings, 5 designates a within therefrigerating chamber and is partially encased by the brine circulatingtank or other cooling means 8. -A pair of compartments 9, Fig. 2, isprovided in the re frigerating chamber adjacent the tank 7 for thereception of bottles 10 or otherarticles tobe cooled. Shelves 11 arearranged in the g'lower part of thecompartm'ent 9 to support the bottlesor other articles which may be placed in the compartments. A second pairof compartments 12 is arranged below the shelves 11 for the reception oftrays or pans 13 whereby icecubes may be made in the A pipe 14 7 andextends through the top wall 15 of the casing 5. This top may be dishedat 16 to support the fiangel? on the pipe 14: and also for the purposeof collectin any water or other fluid which may be spilled on the topofthe casing; I A tubular connecting member 18 carrying a rubber gasket19 is adapted to be inserted into themouth of a water bottle 20. Aflange 21 is arranged on the tubular member 18 to support the gasket 19which extends inwardly of the bottle.

Another gasket or washer 22 arranged about the upper end of thepipe 14and seats on the annular flange 17. This gasket pro I 1 vides ayieldable support or bearing for the tubular member 18 and the bottle 20to which it is attached.

. A valve 23 having a valve stem 24 is prcvided with a'valve disk 25 atits-upper end andit has a crossbar 26 at its lower end which is adaptedto contact with'the upper end 27 of the pipe 14. The valve. stem 24 ismade of such a length that when the tubular member is a plied to thepipe 14 the valve 23 will be lifte by the upper end 27 of the pipe andthereby permit free passage ofthe liquid from the bottle through thepipe14: into the tank ,7. A spring 28 may be arranged about the valvestem 14 for normally holding the valve disk25 against its seat 29 so that noneof th'e'liquid in the bottle will spill when the bottle is ininverted-position and being set in place on the cooler.

Aibottom member 30 is arranged in the casing'5 and below therefrigerating chamher to separate the refrigerating =-chamber fromtheapparatuswhich cools the solution in the brine tank 8. This bottom.member 30 is providedwith' a dished surface31, Fig. 1,

V which communicates with a pipe line 32 for draining the condensationfrom the refrigerating chamber tacle 33. c c V A pipe line .34communicates with'the dished surface'16 in the top 15,; and leads to thereceptacle 33 for draining away any to the drip pan or recepwater vorcondensation which may becollected in the dished surface 16. I I

A verticalstandard 35 issecured to the top of the casing and carriessecuring means (notshown) for maintaining the bottle 20 in properrelative position. 7

- A vent 36 communicates with the storage tank 7 and extends upwardlywithin the standard 35 so that the water will flow readily andquietlywhen the faucet 37, which communicates with thebottom offlthe tank r y 7is operated. The faucet 37 isarrangeddrip from the faucetwill be caughtinth'e bottle inasmuch as the water pressure and casing 5 and extendsover the outlet ends of the atmospheric pressure in the vent willbalance the column of water in the bottlezplus the reduced air pressuretherein.

A baffle 38 is arranged on the side of the the pipes 32 and 34 toprevent them from becoming damaged or filling up with foreigninaterialwr A pair of removable doorsor covers 39 may:- be arrangedin the'top- 15 tof'permit 'accesst'o' the compartments 9.: I I

In practice, the faucet 37 is operated and the pressure in the bottlewill be reduced as the air enters the tank through the vent 34to takethe place of theliquid which is withdrawn This air then displaces thewater standing in the vent; forcing, it down lIltO'the vent before theairrcan gain access to the bottle mouth; after the faucet is closed thewater again rises inthe vent to thelevel determined by the diiferencebetwe'en the thenexisting air pressures in" the vent and" bottle: r

The invention provides a water cooler 1 which is providedwith newandnovel means for providing refrigerated or cooled compartments, and alsoproviding means for making ice 'cubes if and when desired. Changes maybe made inthe form, construction, and arranqementiof the'parts withoutdeparting from the spirit oftheinveir' tion or sacrificing any 0f theadvantages thereof, and the right is herebyre'served to a make all suchchangesas fairly follow with in the Scope of theifollowing Claims. a
